• The filename is the document’s persistent id: frontmatter id for .md (incl. .excalidraw.md), metadata.frontmatter.id for .canvas.
• Each .vh_v2 file holds one focus timestamp per line — ISO 8601 UTC with millisecond precision (e.g. 2026-07-09T12:34:56.789Z) — newline-terminated, sorted ascending, without exact duplicates.
• Per-device directories keep synced devices from ever writing the same file (no sync conflicts).
• Documents whose id is not filename-safe cannot be tracked and are skipped.
